Watersheds and irrigation systems have the characteristic of connecting people vertically by water flows. The location of users along these systems defines their role in the provision and appropriation of water which adds complexity to the potential for cooperation. Verticality thus imposes a...

The dilemma of collective action around water use and management involves solving both the problems of provision and appropriation. Cooperation in the provision can be affected by the rival nature of the appropriation and the asymmetries in the access. We report two field experiments conducted...

This paper explores the link between what people say they prefer to do and what they actually do. Using data from an experimental project exploring trust and pro-sociality for representative samples of individuals in six Latin American capital cities, the paper links the results of these...

This paper explores how wealth and inequality can affect self-governed solutions to commons dilemmas by constraining group cooperation. It reports a series of experiments in the field where subjects are actual commons users. Household data about the participants-context explain statistically the...

Regulations that are designed to improve social welfare typically begin with the premise that individuals are purely self-interested. Experimental evidence shows, however, that individuals do not typically behave this way; instead, they tend to strike a balance between self and group interests....

The use of experimental settings to observe human behaviour in a controlled environment of incentives, rules and institutions, has been widely used by the behavioural sciences for some time now, particularly by psychology and economics. In most cases the subjects are college students recruited...

Economic loss to society due to dishonesty can be quite large. Policy makers use several international indices that characterize countries according to the quality of their institutions. However, no effort has been made to study how the honesty of citizens varies across sixteen countries. This...

Cooperation and competition are both essential elements of economic life. Here we explore how cooperativeness in a prisoner’s dilemma is correlated with competitiveness in a sample of 9-12 year old children in Colombia and Sweden. Using two different measures and four different tasks for...

Policy makers use several international indices that characterize countries according to the quality of their institutions. However, no effort has been made to study how the honesty of citizens varies across countries. This paper explores the honesty among citizens across sixteen countries with...
